Re: preposition

Hello,
welcome in the forum.
The use of with and about depends on the context. Usually every verb/expression has its own preposition.
i.e:
I'll think about that.
What's wrong with you?

Sometimes more than one preposition is possible but it always depends on the context. Here no one can explain to you how these preposition are used in every sentence possible.
Provide a particular situation and you'll find somebody who can help you.

Re: preposition

Personally, I've never heard the expression to be caught up about.
I suppose to catch up with is the correct form but I'm not a teacher. Wait for a teacher to give you better suggestions.
Anyway, the answer still depends on context. Phrasal verbs can carry lots of meaning.
You should say in which kind of situation this phrase would be said.
i.e:James caught up with the car ahead of him.
Do you mean something like this?
You need to provide more information about context.

Re: preposition

which is correct:"i was caught up about something"/ "i was caught up with something"

There's a difference between being caught and being caught up doing something. Here are some ex:

I was caught stealing (red-handed). (accidentally caught in the act)

I found myself caught up in a web of lies. (stuck)

She was caught up doing something in the celler. (busy)

I was so caught up in the magic of your story.! (be involved with)

She couldn't catch up with the rest of the class / catch up with me on the way home. (come from behind, overtake)
_____________________________
also: We have to catch up on what has happened since we left. (get up to date)

"be caught about doing smth"?? haven't heard of it. Maybe: She was taking pictures of people in the streets, caught about their daily business.
